Your thinking process was really an eye-opener for me! It was actually an aha moment to problem-solving in programming! Thanks man
i thought this is like the standard way of thinking for everyone lol
Get one assumption wrong and it could blow your estimation waaay off course...
Yeah, just coming up with random figures doesn't make it analytical. I took the wrong and way too simple method and said probably an average of 10 per borough and came up with 50 which wasn't far from what he had.
I think the point of this video is to illustrate the thinking process. If you were asked a question like this in an interview, the interviewer probably wouldn't care much if you estimated the population of NYC to be 8.5M or, say, 10M (which was my estimate without doing any research and only having some basic high-school geography knowledge). What they would look at is how you approach solving the problem. If you came up with 70-something piano tuners instead of 50-something, that would still be pretty close to Mr Thompson's estimate, and to the actual number of piano tuners he says he found in NYC.
@@BM-uf4pp before watching the full video, I tried to solve the problem as well, with a different approach. In the end, I got stuck, and didn't solve the problem on my own. However, I don't think there is necessarily a "wrong" approach. It just depends on what kind of information you already know. For example, I know nothing about boroughs, or US city structure in general. But I have some basic knowledge about population geography. I don't think his numbers were random. They were estimated based on his general knowledge of the world. For example, he estimated the average size of a household to be 3. Seems legit. Could be 4, could be 2 or 5, we don't know. But he said 3 which seems fine. He didn't say 30. That would be random.
Thank you for making this video, I find it very informative, just what I was looking for...
I was half way watching the video thinking to myself that I really couldnt grasp the concept of it. Thank god looking at the comments made me feel Im not alone. I lost it at when he was spewing random numbers out of nowhere and it ended up confusing me. I got the the part where he chunks the logical steps to be used though
Great Teaching brother! There"s a one thing missing,,,That is Attitude,Just Teach with a enthusiasm And A Smile :)
Households in New York City are less likely to have pianos that need to be tuned due to the fact that most people in new york city do not live on the first floor of buildings, so having a grand piano or baby grand piano would not be ideal over an electric keyboard. Love the way of thinking tho would have never thought to turn the google question mathimatical!
I would have googled piano tuners in New York City and called all of them and asked how many pianos did they turn last year.
😂😂😂😂

Subscribed. These are the content I'm looking for. Clear, direct, concise, solves a real question, and has visuals. You did a good job 👏🏼
I never thought of it as a skill. Struggled as a child and still today. It slows me down. nerve wracking.
The issue with having too many "layers" is that you chain inaccuracies and assumptions together. So if one layer is inaccurate or had the wrong assumption, the end answer will inherit that inaccuracy
I am Mabel Saab, let me first of all thank you for the video, you are excellent in your teaching, and it is well taken. Continue to be excellent in teaching the easy 3 ways To Master Analytical Thinking Without Breaking A Sweat. I love this Course and the presentation. Be.......... bless.
Mabel Saab thanks for the kind words!
Today the word Analytical Thinking come to my Life and then I Critically analyze what that means into a found answer I be an auto technician you need to be A really strong and analytical thinker
Thank you ! your video is really clear and concise ^^
For me is how a particular thing or problem works. Then using my theories I know to help me solve them. Finding the available resources to use. Then application of trial and error and what's best and safest. Lastly, conclusion and remember everything to use them in the future like what to prevent and what are do's and dont's. This is me everyday of my life like I enjoy solving even a single drop of bird poop on the window. I'm nerd and always like being alone and reserved. but "who cares how many piano tuners are there in a certain area, right?"
REI D, he does not care about pianos either. If you are a "nerd" as you claim to be, you would have understood analogies.
Very informative, thank you for sharing man
This sounds just like deductive reasoning.
More like statistical speculation
Sounds like soy
Plot twist : he is a part time piano tuner and
worries about the competion of work in city.
😂😂😂
made me laugh :D
I like this ! I would include that NYC could have a little bit more pianos or tuners since that’s where the Broadway shows are and I image that they have more pianos needing to be tuned !!
I guessed 70, 14 away.
I used demographics to determine likelynesses to determine fairness of a likely acquired skill
That seems more logical. Because I don't see a lot people in the bronx, Jamaica queens owning one
Thank you Sean 👍👍👍
Hi Sean! Do you think we can break down those layers even further and not only include households, but pianos in music stores and concert halls (such as Broadway, etc)? Thank you.
Thanks ... really helpful
Swarna Biswas hi
so analytical thinking is math, oh boy... merging left brain with the right brain thinking is going to be harder than I thought..
thanks, you really helped me!
Amazing explanation
🙌
Very well explanation of analytical thinking process. Thanks
Wow, this was great, thank you!
Thanks
Thank You brother
SuperRudeDog thanks for the feedback!
There are other factors unaccounted for such as schools and performance halls or other establishments (like all the TV studios that have live bands) that would own pianos but not count as households, and then on the converse side there are a large number of low income and medium income households/apartments that don't own a piano. A quick google search says approximately 1-1.5 hours for a basic tune and longer if repairs or pitch correction is needed. Honestly the number of people that do not own a piano wouldn't be balanced out by the number of pianos owned by schools, performance halls and other entities, so we can reduce the number of pianos by half as much but then use 100% of pianos needing to be tuned in a year which basically gets you back to your original number kind of... More specific data is available on household numbers, income, etc... Analyzing information should be done with more specific data IMHO. A piano tuner is likely able to tune more than 2 pianos in a day, especially if a number of clients live close to one another. Other factors would be new pianos need more tuning in the first few years... These last two little bits may be the variants that weren't accounted for that might have been able to give you a closer number to actuality in New York CIty, assuming they only worked directly in the city and the dozens of other factors that change averages and other numbers bit by bit.
Excellent 👍🏻 keep it up 🎉
I got 13 piano tuners when I thought firstly
thank you !
One similar questions asked to my friend during interview is How many white swift cars in india?? -in ZS interview
Misleading video title. I broke both sweat and my brain cells trying to master this.
Really helpful..
Thanks for the feedback. Glad you found the video helpful.
Thanks for your videos.
Absolutely! Glad you enjoy them.
I have an idea. Please comment on me if it is wrong. Check how many piano stores are there and how many piano brands are there in new york city. get a number like 1.5 or 2 on an average of all the stores(some may have 1 and some may have 2. Depending on which place they are in also). And some maybe freelancing it. So it might give a average count much faster.
I was lost when he determined the 20% of the piano needs to be tuned well how do u get to that number I mean some of them break strings some damaged by other factors so how many stays in good condition to be tuned.
hats off brother
Great sir.
Mr burns hand gestures help anlalitical thinkinking lol
I was born with Strong Analytical and it’s so true since I’ve never been unorganised
Here I go again looking for answer but after sometime I'll get tired of it and back to square one.
can we really throw guesses while solving engineering problems?
I must be a geniuses. I guessed 30K after 20 seconds of considering the question. Now if only my LSAT could reflect this...
😂
Okay. I doubt any of us are going to be able to google New York's population during a interview and get all of this information...….. I'm so confused. You wont know that UNLESS you take your phone out in front of the interviewer and google it.
Super but you missed death rate and work force population
the great Radha krishnan You're right. I think those two offset each other. However it's impressive how he was so close to the right answer
There are many piano tuners in Newyork city.
I didn’t understand why He divided the number b(3) specificly ?
Bro, you have said that 5 in 1 person have a piano then we can directly divide the population by 5 then we get the total number of pianos in new york city.
1 in 5*,
Ok then figure how many piano tuners there are to tune them pianos ?
You made an huge assumption that it was only private ownership and private households. It’s ethically vital to distinguish variables (bias, assumptions, etc) when setting up a problem solving model.
Interesting
Can we divide population of New york city from no. piano sold
To think analytically is to move so fast that you see only two frames of you xD 0:21
Confused the shit out of me.
Now I am even more confused then before.
Pianos...
you not alone
Really cool
I was off by 44 Piano tuners
I have an analytical personality. Why not just count the entries in the Yellow Pages?
Could you share any a thing that u r discoved by yourself Abt this topic... just write anything u know
Keep it simple man Google it
ManiDeepu Velivala 😂
This is called "Statistics"
My only disagreement is that analytic think is better thinking rather than a short cut.
this is maths... not thinking process
He threw three guesses in his calculations..how is that analytical?
sean John, you should definitely take my Analytics 101 class. this had nothing to do with Analytical thinking, there were too many untouched variables, and you have not used any firm reasoning in the whole answer, Terrible Example to say the least.
Cant you instead of researching the population's number, simply google the piano tuners?
You have stupid.human brain.
@@renielbernardo6275 So do u. does this look right or did u not see it. Ha😁
So you say but couldn’t say
I wouldn’t agree either
JUNKO FUCKING ENOSHIMA
That Shigen OMG 😂
In India this type of questions are asked in 10th Standard (class).
In india it is common for a cow to become your professor
@@Ħæïķăł yup and cow teaches better than your teachers. We even have buffaloes, sheeps and goats. We just don't have donkeys, I guess because you are in another country.
finally
With all respect, the Google question is a TERRIBLE question for analytical thinking exercise. What reasoning did he use to come up with his guess work? He could just as easily have guessed every house hold has 10 pianos. This is a profoundly flawed lesson. This is so bad, that I find it hard for anyone to think this video teaches you any thing useful. One would have to KNOW how many pianos there are. You would have to KNOW how many pianos a tuner can tune in one day, and if they typically work 5 days a week, etc. You would have to KNOW how often a piano needs tuned. Wild guessing gets you nowhere. I'm not surprised Google uses this kind of reasoning.
This. Analytical thinking is about facts, not guessing. This seems more like an example of logical thinking, not analytical.
There are just too many variables left out of this 'analytical thinking'. Not every household has a piano, for example. I'd say you'd have to take things like average income, space availability (since maybe some people may afford to buy a piano, but don't have that much space to put it, specially in NYC...), personal preferences, etc. There's no accurate answer to this question, even if one uses actual statistic numbers.
The question isn't the issue in this case hes explaining the process of analytical thinking which is what most people clicked on the video for, realistically speaking no one came here looking for the answer of how many pianos are tuned, instead by learning the methodology of how he approached it is the key to take from this video not the question itself
@@ultrazenom1500 correct they're only hypothetical information.
Yeah, I found myself rolling my eyes at every estimation in the video. This method is a total flop. What if someone knows nothing about pianos and just making wild assumptions. That isn't very analytical or useful.
Don't know but that was kind of a bad example. why would you do it the way you did? Just google it..
I think the real analytical part comes after you have the number of piano tuners. Cause what does that number tell you. What do you want to do with that number?
I never knew anyone who owned a piano
But you are wrong because there might be a piano nerd who own 10 pianos or more and tune them all himself. Or maybe 10 of those nerds which makes up to 100 pianos. And you only counted the registered tuners. You have no clue if it takes 3 hours to tune a piano? All things you are saying is just random guesses. Plus that also companys, music stores, schools, operas etc. might be having pianos so they are not even included in the households. There are so many aspects so it is absolutely impossible to think that way.
If you want to check if your thinking is analytical, here's a question: A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost? So if you solve this one correctly than you know the meaning and application of analytical thinking. If not, you're a logical thinker.
The bat costs $1.05 and the ball $0.05?
@@dcad6934 yeah, but that is not the point.
I’m confused bro. What’s the answer to the question?
dc ad what made you think that?
@@thajoseph2079 what question?
Why don't you just Google how many music shops that sell pianos. And however many music shops that sell music shops there will be one person per shop that work at the music shop that sell pianos. So if there are 20 music shops that sell pianos then there are 20 people in New York that tune pianos.
If you ever need an Editor I will edit your videos for a small fee. Your information far exceeds the production quality of the video. No offense. Everyone has there strong points
I would have said there is 1 piano every 1000 people and one piano tuner every 1000 pianos. That makes arround 8,5 piano tuners. Wich is probably wrong.
Let's say 1 piano every 500 people and one tuner every 500 pianos (how would they pay their bills if the ratio was lower). Now we have 34 piano tuners. That is more reasonable.
Additionally I don't think a piano tuner tune two piano per day. They'll all be rich if that was the case. It must be something more like two per month.
I followed his link to yelp search results for best piano tuning and a hole lot of the results are piano movers or stores, what makes my prediction more correct (even knowing most piano tuners don't have obligation to be in yelp)
I say there's a100
This guy would probably get a 60 on the lsat.
I caught 4:12 it's not 566000 it should be 566600
That’s not what analytical reasoning is
And this is why marijuana need to stay illegal
Marijuana makes people dumb it is true!!!
Rollerskates yeah that’s right before the age of 23 your brain isn’t fully developed and weed deletes brain sails. but i don’t think dumb is the right answer considering that dumb means unwilling or unable to speak ha-

@@riversworld5794 Actually the prefrontal cortex takes about 25yrs to mature on avg & even longer for some
LOL! Please don’t do what this guy says.
Well what should we do?^^
Whyy
Can't the answer be :
:Less than the population of the New York city?
too much pianos i already got lost
.....those NYérs can they play Piano ?
Virgos understand exactly what analytical thinking is. Lol.
What he was explaining is the art of approximation. He messed up by not telling you that this type of analytical thinking is not a form of thinking to find an accurate answer. Instead is to see how a person thinks. In Google interviews for an example, they will ask questions you can't answer because they don't want the accurate answer they want to know how your mind would go about answering a problem without knowing anything about it. How else do you think INNOVATION works? We don't know everything in the world so we have to use our own logic and reasoning to make up numbers that fit that logic. Our technology wasn't built upon accurate thinking. It was built upon logic and reasoning. You can't know everything, but you can make a complex problem easier.
The method is often used in real-time business situations to scrutinize information that is presented. As a consumer of data/info you can use this to accept / reject / challenge bad/misleading data….happens all the time.
This is logical reasoning with estimation. Not analytical thinking.
That’s what I think too 😃
You haven't been to the bronx or Jamaica queens
why?
Oh dear..... This is the exact opposite of analytic thinking. Start by defining what a piano tuner is. Somebody who can tune a piano, are the all working full time or even working. Can they be retired?
A lot of guessing and ending up whith a number that is close to something?
ASSUMPTION IS THE MOTHER OF ALL FUCKUPS!
Poul Thomsen....
Clearly u rnt used to how science is done and how scientific analysis and experimentation are conducted....
do you really have to hold your hands like that for the whole time lol
Lol 1 per household? No
He said 1 in 5 households.
May be you should rename this video as 'How many Piano tuners live in NYC?' Because sorry mate, this is not teaching analytical thinking process.
Disliking this video just bcoz of too many advertisement
I got 3 ads. What's wrong with that?
@@jaycharles6441 hey i watched all your videos nothing wrong in that. Your videos are awesome. 👍But that time TH-cam showing me so much adds on your videos. I think 4-5.
